Remap Stock Ecu With "nissan Edit"

[ob1]

i was chatting to Mercury Motorsport yesterday about a new product they are selling. They will replace the read-only ROM in your ECU with a programable EEPROM and tune it in realtime on the dyno with some software called "nissan edit" (apparently developed by "dr drift" tuning in Victoria).

Has anyone had any experience with this method of ECU tuning?

Sounds like a neat way to get new ECU maps...no replacement of the ECU unit required.

They quoted me $750 for the mod and 2hrs dyno time on my R34 gtt. Normally $960, but its on special being a new product (prolly need some guineapigs to get used to the new tuning software)

Sounds like a bargain, but i'm trying to work out if there are any downsides compared to other ECU chips/piggybacks/replacements.

They haven't been getting the results they should have and I think this is all about practice. It can work well but the first people getting it - and there are a few already are not getting the value.

Are you auto or manual?

[ob1]

manual....i asked if there was a difference (life the SAFC that doesnt work with auto) and he said this method works with both.

i'll be in at Mercury Motorsport getting my ECU tuned tomorrow and will post results when i have them

Abo bob - are you talking about the same place? they are in brisbane and you're in sydney...

anyway, they have the software that Sam (aka Dr Drift) uses and he'll be there tomorrow and the next day training the guys in using the software etc.

They know how to tune cars already - they are well versed in the power FC, ecutek, and other aftermarket ECUs. they just have to learn the software

anyway i'll let you know how i go

cheers,

I reprogrammed the chip in my Z32 300zx tt, got awesome results. Once you get the hang of it its really quite easy.

[Godzilla32]

My understanding of it after reading the HPI it was featured in is: They create a state of tune right for your car with its current setup then burn the data to the eprom chip and install it into your standard ecu. Therefore its not adjustable. Once its done it is set until you get a new chip remapped for a different setup.

[Guest 40th-edition]

for the cost would it be worth getting a apexi pfc that is tuneable?

any advantages with this system other than cops not knowing!

[WazR32GTSt]

the advantage is that you ratins knock adjustment, cold start, etc.

if you go back to the same place then they can keep your tune on their computer, and when adding a mod to the car they simply change a few parameters and burn a new chip..

the only difference to the powerFC is that you have to re-install a new chip each time. other then that there's no difference. car is still tuned on teh dyno with a computer its not a plug ang play option like some of the "chips" out there...

oh, and there's no initial outlay like the $1000+ you pay for powerFC and hand controller

[mjfawke]

As only the earlier 8-bit ECCS ECU's have a separate ROM (Z32/R32) etc, and the R33 onwards use a 16 bit one-time-programmable processor, how do they tune the later cars? Do they retrofit an earlier ECU?

[WazR32GTSt]

if you read their website, they can't do R33 ECUs at the moment...

[mad082]

there is someone in brissy doing r33's. my mate fried his 33 ecu (talking hole in the chip) and sent it to them and they sorted it out. they had tuned the ecu in the first place, and did another chip for him. rev limit at 7600, no speed cut, no r&r, etc.

Once its done it is set until you get a new chip remapped for a different setup.

Well thats kinda true and kinda not true

With both the standard ECU and the PFC, you tune them for your current mods, the day, they dyno etc etc, then set the timing and fuel based on that.

From there, when you change anything like a little more boost or a zorst, you will no longer have the best tune for your mods....but in many cases you just move around the map a little but still get good results.

But if you want to get back to a "best" tune you will need to retune it......whether PFC or standard.

With the later computers you can put a new EPROM daughterboard that lets you tune, but the 32 computers can be tuned straight up

[Abo Bob]

I'm talking about Sam. I like the idea of knock protection however I blew my engine with one of these in it so it obviously doesn't work.

If you have a manual then I still think the PFC is the way to go. If auto then a little persistance will pay off - for the people after you.

Waz, you have an R32. Completely different and well known by tuners, including Sam. This is fairly new to R34's and different rules apply.

[MerlinTheHapyPig]

Installing the chip, is just a matter of soldering a socket in place of the stock rom, this is a 30 minute job + $10 parts for the socket and blank eeprom. $750 is quite high as a up-front cost.

I didn't know you could do R34's, i though you needed a daughterboard... anyway. If this is included it would add more to the cost.

Make sure the tuner is using the latest version of the emulator and software, because only the later eprom emulator hardware will be able to do a "map trace". With the older software (freely availble, it's called Live Edit) you can't do map traces, the newer version NRE is much better but the old-school emulator hardware won't work for Map Traces.

mercury motorsport only got the software recently (as in this month) as sam was up here in QLD last week showing them how to use it...

so tis new software

i am delting my post coz i cbf arguing

dont waste you money just buy a power fc trust me , and if car is auto convert to manual

i'm after an informed decision, not an emotional one....can you actually ellaborate on why a PFC would be the better option?

[mad082]

well if it is an auto r32, i would be looking at every option before converting to manual and putting a pfc in. there is a huge difference in price. especially if it is a r32. the cost difference between a r32 remap, and getting a pfc and manual conversion is a well over $1000.

i run a remapped ecu in my 33. haven't had any issues with the ecu.

[MerlinTheHapyPig]

if the tuner is good, a remap can do almost everything a power fc can do.

If you have an automatic, it is the best option. The downside to remaps are that there aren't many places that do it.
